Proper maintenance is essential to extending spark plug life. Careful reconditioning allows spark plugs
to be reused at a far lower cost than replacement. Adhere to a scheduled service interval as
recommended in this section. More stringent intervals may be required based on multiple submersions,
heavy fuel use, operating conditions or personal experience.
Removal

Prior to removing spark plugs for inspection and servicing, examine the area surrounding each
spark plug for damage or missing components that may or contribute to or potentially lead to
degraded performance.

Carefully pull each plug boot connector straight out. Avoid side pressure, which may damage the
terminal sleeve or the barrel insulator.

Examine the Boot Extensions, replace cracked, arc tracked, or otherwise damaged.

Visually inspect the boot and ignition contact for evidence of arcing or other damage.

Remove each spark plug with a 16mm deep well socket. Carefully seat the wrench securely on
the plug to avoid damage to the threads or barrel.
Inspection

Visually inspect. Dispose of plugs with
worn, damaged, or cracked, Terminal
Ends, Insulators, threads, electrodes, or
other parts.

Optimal, indicated by a brownish or
caramel color on the porcelain firing end
with few deposits. Electrode is slightly
worn, but not eroded or burned.

Lean, indicated by a dry whiteish texture
on the porcelain firing end. In the worst
cases the tip of the plug starts melting
away.

Rich/Oil, indicated by dark discolored
porcelain, oil spillage on the tip of the plug.
Also, the spark plug might be slightly wet
on its thread.
Never install a spark plug that has been dropped (even if there is no visible sign of damage). Dispose
of the dropped spark plug and replace it with new.
